Abstract

TEIXEIRA, Tatiana Rodrigues de Araujo  and  MEDRONHO, Roberto de Andrade. Socio-demographic factors and the dengue fever epidemic in 2002 in the State of Rio de Janeiro, Brazil. Cad. Saúde Pública [online]. 2008, vol.24, n.9, pp. 2160-2170. ISSN 0102-311X.  http://dx.doi.org/10.1590/S0102-311X2008000900022.

This study analyzed the dengue fever epidemic in 2002 and the socio-demographic context of the State of Rio de Janeiro, Brazil, using spatial analysis and statistical modeling. The incidence rate was calculated for resident dengue cases in the State in 2002. The study analyzed associations between incidence and socio-demographic variables and spatial autocorrelation using the Moran Global Index, which showed spatial dependence for both the outcome and the independent variables. A multivariate linear regression model was used. The variables' proportion of urban population, percentage of the population with running water, and percentage of coverage by the Family Health Program (FHP) explained 30.2% of the total variance in the epidemic's incidence rate. The model's residuals did not show spatial autocorrelation. The associations were in the expected direction, and the findings are corroborated by other studies that showed higher dengue incidence in areas characterized by growing urbanization and deficient running water and water supply, while highlighting the FHP as an important facilitator of vector control strategies.
